OBJECTIVE To further characterize the demographics, outcomes, and prognostic factors for refractory status epilepticus (RSE). DESIGN Retrospective analysis of all the episodes of RSE treated between January 1, 1999, and August 30, 2011. SETTING Neurointensive care unit within a tertiary referral center, Mayo Clinic, Rochester, Minnesota. PATIENTS(More)
OBJECTIVE To describe clinical characteristics and immunotherapy responses in patients with autoimmune epilepsy. DESIGN Observational, retrospective case series. SETTING Mayo Clinic Health System. PATIENTS Thirty-two patients with an exclusive (n=11) or predominant (n=21) seizure presentation in whom an autoimmune etiology was suspected (on the basis(More)
IMPORTANCE A focal lesion detected by use of magnetic resonance imaging (MRI) is a favorable prognostic finding for epilepsy surgery. Patients with normal MRI findings and extratemporal lobe epilepsy have less favorable outcomes. Most studies investigating the outcomes of patients with normal MRI findings who underwent (nonlesional) extratemporal epilepsy(More)
OBJECT Surgical treatment options for intractable seizures caused by a nonlesional epileptogenic focus located in the central sulcus region are limited. The authors describe an alternative surgical approach for treating medically refractory nonlesional perirolandic epilepsy. METHODS Five consecutive patients who were treated between 1996 and 2000 for(More)
OBJECT Patients with normal MR imaging (nonlesional) findings and medically refractory extratemporal epilepsy make up a disproportionate number of nonexcellent outcomes after epilepsy surgery. In this paper, the authors investigated the usefulness of intracranial electroencephalography (iEEG) in the identification of surgical candidates. METHODS Between(More)
We performed a retrospective study of 51 consecutive patients who underwent operation for intractable partial epilepsy related to low-grade intracerebral neoplasms between 1984 and 1990. All patients had medically refractory partial seizures and a mass lesion identified on neuroimaging studies. Lesionectomy was performed on 17 patients, and 34 had lesion(More)
OBJECTIVE To determine the functional and cognitive outcomes of patients with prolonged refractory status epilepticus (PRSE) lasting 7 or more days despite the use of anesthetic agents for seizure suppression. DESIGN Retrospective analysis. SETTING St Mary's Hospital, Mayo Clinic, Rochester, Minnesota. PARTICIPANTS Fourteen patients with PRSE. (More)
Ictal asystole may contribute to seizure-related injury and mortality. The purpose of this study was to evaluate the effect of cardiac pacing on seizure-related injury rates in ictal asystole patients. A survey was conducted to determine seizure-related fall rate and other morbidity in all seven patients with ictal asystole who underwent cardiac pacing at(More)
OBJECTIVE The occurrence of asystole during an epileptic seizure is the most dramatic manifestation of ictal bradycardia. Recognition of ictal asystole is important as treatment with both antiepileptic drugs and cardiac pacing may be necessary. The purpose of this study was to identify clinical cues to aid in the detection of ictal asystole. METHODS We(More)
OBJECTIVE To evaluate the cancer detection rate of whole-body positron emission tomography-computed tomography (PET-CT) in a paraneoplastic neurologic context. DESIGN Retrospective medical record review. SETTING Mayo Clinic, Rochester, Minnesota. PATIENTS Fifty-six consecutive patients with clinically suspected paraneoplastic neurologic disorders who(More)
